CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 14/524,658, filed Oct. 27, 2014, which claims the benefit of U.S. Application Ser. No. 62/054,572, filed Sep. 24, 2014, each of which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

Log data recorded by a system (e.g., a server, a gateway device, a network router, a firewall, etc.) are footprints of system and/or network activities. When the system experiences an anomaly, which may be due to various reasons (e.g., attacks, virus, phishing, electricity outage, etc.), a system administrator typically relies on the system log data to identify problems in order to carry out a solution. However, in the modern computing infrastructure which includes a tremendous number of computing devices, more system and network activities take place, leading to more log data being recorded.

SUMMARY OF THE INVENTION

A large number of recorded log data occupies a large volume of data storage; in some cases, a gigantic amount of log data may induce system failure. Moreover, the raw log data are unstructured log data, which prohibits systematic management of system/network events. When a system outage happens, the more log data, the more difficult the outage can be to solve and the more time the system administrator must spend to discover the true source of the outage. It has been estimated that the loss due to system downtime can reach as high as 5 million dollars per hour, for example, in the financial industry. A new way to record log data occupying a smaller volume of data storage is an urgent task. Moreover, an easy way for system administrators to monitor, analyze and manage log data is needed.

In addition, the system/method/media disclosed herein will assist system administrators in identifying anomalies in a short amount of time.

DETAILED DESCRIPTION OF THE INVENTION

A drawback of existing schemes of log data handling is that a large number of recorded log data occupies a large volume of data storage. The drawback may further induce system failures. Another problem is that the raw log data are unstructured log data, which prohibits systematic management of system/network events. Furthermore, it has been frequently seen that an unusual activity takes places in a number of trials during a small time window. For example, a computing system may repeatedly attempt to access a same hard drive which is out of order. In a phishing activity, a hacker attempts to access sensitive information with a large number of trials during few seconds, minutes, or hours.

Due to various reasons ranging from power blackout to network attacks, a system outage happens from time to time; the more log data, the more difficult the outage can be solved and the more time the system administrator must spend to discover the true source of the outage, which could be failure of an uninterruptible power supply or a network attack. Financial loss due to system downtime can reach as high as 5 million dollars per hour in various industries. A more catastrophic scenario is data breach or security outbreak. In the worst cases, the system outage may sacrifice human lives. The faster the system administrator can find the actual problem and carry out efficiently an effective solution, a smaller loss will incur. Therefore, a new computing infrastructure able to handle a tremendous amount of log data is necessary. A new way to record log data occupying a smaller volume of data storage is an urgent task. An easy way for system administrators to monitor, analyze and manage log data is a must.

The subject matter disclosed herein includes a new system, a new method, and/or new media to record system log data. Furthermore, the subject matter comprises a novel analysis paradigm to assist log data monitoring and management. In particular, when there is an unusual activity which takes place a number of times during a time window, the system can analyze the log data, reduce the storage size required to store the log data, detect the abnormality, and alert the system administrator. The system described herein can save a large amount of data storage and can scale up the log data management to virtually infinite servers. In addition, the system/method/media disclosed herein will assist system administrators identify system outage in a short amount of time. The benefits include, but not limited to: lower cost of computing infrastructure, lower cost of data storage, high speed of log data storing, generation of structured log data from raw log data, removal of duplicated information in the raw log data, smaller amount of required data storage, efficient management of log data, less system outages, faster problem solving during system outages, and less financial loss.

CERTAIN DEFINITIONS

Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. Any reference to “or” herein is intended to encompass “and/or” unless otherwise stated.

Raw Log Data

In some embodiments, the system, network, method, and media described herein include log data or raw log data. In some embodiments, log data are generated by a computing system; non-limiting examples of computing systems include: email servers, web servers, FTP servers, gateway devices, routers, switches, desktop computers, tablets, phones, mobile phones, hotspots, printers, hard drives, data storages, security systems, access control systems, surveillance systems, or any system which can generate log data. The generated raw log data are unstructured text strings. A string of texts may contain various types of information; non-limiting examples include one or more IP addresses, timestamps, activities, activity types, resources accessed, user agents, access types, etc. In fact, the information contained in the raw log data is useful, but the unstructured log data prohibits system administrators to fully utilize the information contained therein. Therefore, the subject matter disclosed herein further transforms the raw log data into structured log data using one or more parser modules.

Parser Module

In some embodiments, the system, network, method, and media described herein include one or more parser modules. In some embodiments, a parser module receives raw log data from a computing device, such as email servers, web servers, FPT servers, gateway devices, routers, switches, desktop computers, tablets, phones, mobile phones, hotspots, printers, hard drives, and/or data storages. The parser module further transforms the raw log data into structured log data. In some embodiments, the transformation comprises processing the raw log data by a hash function, deriving one or more system event identifiers from one or more data fields of the raw log data. In some embodiments, the transformation further comprises generating the structured log data in a binary format.

The structured log data comprises the data fields (or called tokens in the programming language) extracted from the raw log data. The data fields are well organized in the structured log data, based on the use of various types of data structures. Non-limiting examples of the data fields include: timestamps, IP addresses, system events, activities, activity types, resources accessed, user agents, access types, device information, system information, hardware/software information of devices, etc.

Furthermore, the structured log data comprises information derived from the raw log data, or derived from the data fields extracted from the raw log data. The information derived includes one or more system event identifiers. In one embodiment, the system event identifiers comprise an alphanumeric representation of a system event. In another embodiment, system event identifiers comprise a checksum. Non-limiting examples of system events include a network event, an actionable network event, system failure, network failure, a user activity, a phishing activity, a spam, an advertisement, a fake message, a hack, an attack, an intrusion, a malicious activity, an unnatural activity, a virus, etc.

System Event Identifier

In some embodiments, the system, network, method, and media described herein include one or more system event identifiers. A system event identifier is a numeric, an alphabetic, or an alphanumeric representation of one or more system events. A system event identifier is derived from processing the raw log data. An event and an activity are used interchangeably in this disclosure.

In some embodiments, an activity takes place a number of times during a time window, where the time window is predefined or adaptively determined by the system. The repeated activities may be normal (e.g., a high-frequency trader places 1000 trades within a second) or abnormal (e.g., a hacker attempts 600 times to break a network firewall to steal customer credit card information stored in an online store). The parser module identifies the repetitions of the same activity, and assigns same system event identifiers to the same activities.

Once a system event identifier is derived, it is stored in data storage, such as volatile memory device or non-volatile data storage device. In some embodiments, the identifier is stored in a volatile memory device; the identifier is pushed by a parser module to a storage module, or is pulled by a storage module from a parser module. In some embodiments, the identifier is stored in a non-volatile storage device; the identifier is retrieved by the storage module locally or remotely, alternatively, the identifier is transmitted from a parser module to a storage module via a communication mechanism.

In certain embodiments, the derivation of a system event identifier is contingent on a time window. As described in the previous paragraph, an activity may happen just one time, or few times, or a large number of times. The importance of the number of occurrences associated with a same activity depends on a time window. For example, a user logs into a system with 1000 times per year may not pose a serious problem; however, it is a red flag if the 1000 logons happen within 5 seconds. Therefore, the subject matter limits the derivation of a system event identifier within a time window. When identical activities take place in two different time windows, the activities are associated with two system event identifiers, each of which is related to one of the two time windows.

In some cases, when the same activities happening in different time windows are further associated with another factor or other factors (e.g., IP addresses, regions, resources accessed, etc.), the activities are all assigned same system event identifiers. For instance, identical spam emails are sent out thousands of times every morning 8 am-9 am; if a time window is defined as 1 hour, the spam emails sent out yesterday and today would be mapped with two different identifiers. Nevertheless, when analysis further recognizes the spam emails were from the same sender, the subject system assigns all the spam events with same identifiers.

In some embodiments, the time window is predefined by a system itself or by a system administrator. In other embodiments, the time window is determined adaptively or dynamically by the system, based on an analysis or based on a rule set by a system administrator. During the time window, the structured log data comprising system event identifiers is accessed by a storage module. When a time lapses the time window, the system event identifiers are inaccessible by the storage module.

Storage Module

In some embodiments, the system, network, method, and media described herein include one or more storage modules. In some cases, a storage module utilizes a database service (e.g., MySQL) for storing the structured log data. In other cases, the storage module does not use a database service at all for storing the structured log data.

In the embodiments where the storage module does not use a database service, the storage modules are configured to perform one or more of the following steps: receive the structured log data; identify duplicated data entries in the structured log data, wherein the duplicated data entries are associated with a same system event identifier; create a representative of the duplicated data entries; count a number of occurrences in the duplicated data entries; retain timestamps of the duplicated data entries; generate a serialized data record and store the serialized data record into the one or more binary files, wherein the serialized data record comprises: the timestamps, the representative, and the number of the occurrences; and retrieve the serialized data record from the one or more binary files.

In some embodiments, identical activities take place a large number of times within a time window. The activities may be normal (e.g., a high-frequency trader places 1000 trades within a second) or abnormal (e.g., a hacker attempts 600 times to break a network firewall to steal customer credit card information stored in an online store). The repetition of an activity means that a large number of storage is occupied for recording the repeated activities in the raw log data and/or in the structured log data. In some cases, the large number of recordings themselves leads to system crash.

To avoid the data storage problems, the storage module deduplicates the data entries in the structured log data. In other words, the storage module searches duplicate data entries in the structured log data. The duplicate data entries are associated with the same system event identifiers. As such, to store the structured log data with less storage spaces, the storage module makes a single representative of the duplicated data entries, and stores only the representative without having to store all the duplicate data entries. On the other hand, although a same activity repeats a number of times, each of the repetitions is associated with one or more different determinants, such as timestamps, users, senders, receivers, resources accessed, activity sources, IP addresses, etc. Therefore, the storage module further retains and stores one or more of the different determinants. In further embodiments, the storage module generates one or more summaries of the duplicate data entries. Non-limiting examples of the summary include: the number/list of occurrences in the duplicated data entries; the number/list of sources of the repeated activities; the duration of the repeated activities; the number/list of senders; the number/list of receivers; the number/list of accessed resources; the number/list of device types; and any information associated with the repeated activities.

Binary Format

In some embodiments, the data entries of structured log data are stored in a binary format, or in a binary file. In addition, the storage module stores the deduplicated data entries, determinants, and summaries as data records in binary files. Storing in binary format or binary files (opposed to text strings or SQL database entries) can significantly save the storage space. In addition, the data records are serialized in order to further efficiently use the data storage.

The numbers of bytes occupied by data fields are determined in a systematic manner. For instance, a timestamp occupies 1 byte, or 2 bytes, or 3 bytes, or 4 bytes, or 5 bytes, or 6 bytes, or 7 bytes, or 8 bytes, or 9 bytes, or 10 bytes, or more than 10 bytes, or more than 15 bytes, or more than 20 bytes, or more than 30 bytes, or more than 40 bytes, or more than 50 bytes. A virtual offset comprises 1 byte, or 2 bytes, or 3 bytes, or 4 bytes, or 5 bytes, or 6 bytes, or 7 bytes, or 8 bytes, or 9 bytes, or 10 bytes, or more than 10 bytes, or more than 15 bytes, or more than 20 bytes, or more than 30 bytes, or more than 40 bytes, or more than 50 bytes. A binary file identifier takes 1 byte, or 2 bytes, or 3 bytes, or 4 bytes, or 5 bytes, or 6 bytes, or 7 bytes, or 8 bytes, or 9 bytes, or 10 bytes, or more than 10 bytes, or more than 15 bytes, or more than 20 bytes, or more than 30 bytes, or more than 40 bytes, or more than 50 bytes. A representative of repeated activities (or, of duplicate data entries in structured log data) uses 1 byte, or 2 bytes, or 3 bytes, or 4 bytes, or 5 bytes, or 6 bytes, or 7 bytes, or 8 bytes, or 9 bytes, or 10 bytes, or more than 10 bytes, or more than 15 bytes, or more than 20 bytes, or more than 30 bytes, or more than 40 bytes, or more than 50 bytes.

Note that depending on the type of computing systems, the number of bits in a byte may differ. Those with skill in the art can easily recognize the optimal allocation of the number of bytes for the data fields.

In some embodiments, the storage module further comprises an online analytical processing tool configured to aggregate a data field in the one or more binary files. Non-limiting examples of the data field includes: the timestamp(s), the number/list of occurrences of a host server, the number/list of occurrences of a program, the number/list of occurrences of a severity level, the number/list of occurrences of a system event, the list of a last active host server, a summary of system events within a time window, the number/list of occurrences in the duplicated data entries, the number/list of sources of the repeated activities, the duration of the repeated activities, the number/list of senders, the number/list of receivers, the number/list of accessed resources, the number/list of device types, and any information of interest.

Data Storage

In some embodiments, the system, network, method, and media described herein include one or more data storages, or the use of them. In certain embodiments, the one or more data storages comprise one or more types of storages, where the storages can be volatile or non-volatile. The storage is one or more physical apparatuses used to store data or programs on a temporary or permanent basis. In some embodiments, the device is volatile memory and requires power to maintain stored information. In some embodiments, the device is non-volatile memory and retains stored information when the digital processing device is not powered. In further embodiments, the non-volatile memory comprises flash memory. In some embodiments, the non-volatile memory comprises dynamic random-access memory (DRAM). In some embodiments, the non-volatile memory comprises ferroelectric random access memory (FRAM). In some embodiments, the non-volatile memory comprises phase-change random access memory (PRAM). In other embodiments, the device is a storage device including, by way of non-limiting examples, CD-ROMs, DVDs, flash memory devices, magnetic disk drives, magnetic tapes drives, optical disk drives, and cloud computing based storage. In further embodiments, the storage and/or memory device is a combination of devices such as those disclosed herein.

In certain embodiments, the data storage is used by the parser module, or by the storage module, or by both the parser module and the storage module, or by any other modules included in the system described herein.

In some embodiments, the system, network, method, and media described herein include a mapping module. The mapping module is configured to create, record, modify, or delete a map between the one or more system event identifiers and the storage module. In some embodiments, there are a plurality of parser modules and a plurality of storage modules. When a parser module generates structured log data, it is the turn of a storage module to analyze the structured log data. Recall that a task of storage modules is to deduplicate the data entries in the structured log data; i.e., the storage module will generate a single representative of duplicate data entries, which in some embodiments are determined as associated with the same system event identifiers. Therefore, the structured log data related to the same system event identifiers are designated to the same storage module. Otherwise, the designation of the structured log data to two distinct storage modules will waste the storage space and computational power.

Detection Module

In some embodiments, the system, network, method, and media described herein include a detection module. The detection module is configured to detect a system event/activity from the structured log data, or from the one or more binary files, or from both of the aforementioned.

In some embodiments, the manager module itself comprises a data storage storing one or more configuration parameters of the parser/storage module.

In some embodiments, the system, network, method, and media described herein include more than one parser module, or more than one storage module. Therefore, the manager module further comprises a networking map of the parser module(s) and/or the storage module(s). The network map comprises a geographic location and/or an IP address.

System Event Management

The modern age of cloud computing boosts a large number activities on the Internet, leading to tremendous recordings in raw log data. Storing huge sized raw log data becomes a formidable task, slowing down computational speed and wasting computational resources. In addition to the aforementioned deduplication technology, exploitation of knowledge of well-known events can facilitate log data analysis and management. For example, a computer worm has been well investigated and a method to block the worm is known. When the worm reaches a system, the system can automatically or manually invoke the antivirus program to block or kill the worm.

In some embodiments, an event filtering mechanism is applied when the system receives unstructured, raw log data. In some embodiments, the event filtering mechanism is applied when the structured log data is generated. Alternatively, the event filtering mechanism is applied when the deduplicated log data is generated. The filtering mechanism relies on a database of known events. The database can be based on SQL technology, or based on storing known events in a binary file as deduplication did.

The filtering begins with determining if an event has been seen. In case the event was unknown, the event was presented to a system administrator for further evaluation. The human evaluation determined what action should be acted when such an event occurs, and the knowledge was further stored in the database. In case the event was known, the following question was explored: “if the event is an actionable event?” If not actionable, the event was kept for further analysis. If actionable, the system automatically performed an action associated with the event, or requested a system administrator perform an action.

In some embodiments, the event filtering in conjunction with log data deduplication amplifies the capacity of the deduplication system. Some events can be handled automatically by the system. Some trivial events will not be presented to system administrators. In particular, when fewer non-critical events are seen by the system administrator, they can address the events that indeed require their attentions.

EXAMPLES

The following illustrative examples are representative of embodiments of the software applications, systems, and methods described herein and are not meant to be limiting in any way. While preferred embodiments of the present invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed in practicing the invention.

Example 1 System Design

FIG. 1 illustrates an example of a system design. In this example, the parser module received network/system event which were recorded in unstructured, raw log data. The parser module pulled the raw log data and assigned multiple workers to transform the raw log data into structured log data, where was pushed to the storage module. The storage module pulled the structured log data, where the deduplicator identified duplicated data entries in the structured log data and removed replicate data entries. Finally, the deduplicated data was stored into one or more binary files in data storage, which was linked with a full text searching (FTS) backend. On the other hand, the configuration module passed configuration parameters to the storage module for setting up (or updating) the optimal configuration of the storage module.

The system decoupled the core process/analysis modules from the front user interfaces by including one or more application programming interfaces (APIs). Referring to FIG. 1, there was an API in the storage module. This API allowed a user or another computer program to access the information stored in the storage module or to configure the storage module. Furthermore, there was an aggregating API, which can integrate various pieces of data stored in different storage modules. In the configuration module, it contains a configuration API to communicate with the storage API for parameters passage. The benefit of API design was to allow a third party to create its own software application.

The subject matter implemented in this example produced an unexpected, promising result. The system was able to process approximately 1 million events per second, which was a 66-fold increase in scalability compared with a benchmark system. Similarly, the ingestion, indexing and search of system events/activities were made at unrivaled speeds. Another benefit of the system in this example was the capability of handling enormous amounts of unstructured raw log data. The duduplication technique significantly reduced space for log storage, and in turn enabled the system to store more log data.

The stored log data was no more a mess; it was in a well-organized format allowing a system administrator to not only monitor what had happened in the system but also manage an optimal configuration/allocation of computing resources. Important events hidden in the raw log data usually are a small portion, which is difficult for system administrator to monitor and manage. Through the effective management in this example, the

Example 2 Event Filtering and Management

In the modern age of computing, a large number activities taking place in a system are recorded in raw log data. Storing the raw log data becomes a formidable task, which slows down computational speed and wastes computational resources. The subject matter described herein can solve the problems, as shown in the example described in FIG. 1. Nevertheless, there have been a number of events well known to system administrators; the knowledge can be organized in a in a knowledgebase or data store, which is further exploited to management events.

FIG. 2 illustrates an example workflow of event filtering. When the system received unstructured raw log data (or deduplicated log data in another embodiment), a database of known events was invoked. The major task at this step was to determine “if an event has been seen?” If the event was unknown, it was presented to a system administrator for further evaluation. The human evaluation determined what action should be acted when such an event occurs, and the knowledge was further stored in the database.

If the event was known, the following question was: “if the event is an actionable event?” If not actionable, the event was kept for further analysis. If actionable, the system automatically performed an action associated with the event, or requested a system administrator perform an action.

The event filtering based on existing knowledge assisted system administrator to efficiently manage events. Moreover, the event filtering in conjunction with log data deduplication would augment the capability of the whole system. In particular, fewer non-critical events would be seen by the system operations personnel, allowing them to address only the events that need attention.

Example 3 User Interfaces

FIG. 3 to FIG. 5 illustrate an example of a user interface. The user interface presented an overview of the system, with user definable multiple dashboards comprising different set of portlets. Each portlet was customizable and could be arranged to the user's liking. Time based charts could zoom into smaller time windows, e.g., months, weeks, days, hours, minutes, and/or seconds. When seconds were selected, the graph turned into a “live” chart showing incoming event summaries.

The system comprised various components, e.g., facilities, host servers, and programs. The user could interact with the dashboard to view a status or a summary of the system components. Furthermore, the system analyzed the raw log data and performed deduplication, and a user can view the summary of the deduplication, e.g., number of events, the time series of the received events, servers associated with deduplication, IP/MAC addresses associated with the events, browsers associated with the events, and alerts.

Referring to FIG. 4, the interface presented a summary of computing resources (such as CPU, hard drives, and memory devices) used for log data processing. The summary could be a snapshot or a time series. In addition, the hardware conditions (e.g., temperature, system load) were displayed.

FIG. 5 presents an example of detailed log data information. Once the parser modules and storage modules finished removing duplicate data entries and storing them into binary files, the log data information could be retrieved by a full text search tool. Using the retrieval tool, the system events were summarized, e.g., in terms of severity over time. Furthermore, a list of system events was displayed for the system administrator to monitor the system status.

Example 4 Detection and Alert

FIG. 6 to FIG. 9 illustrate an example of detection results and alert results. Referring to FIG. 6, when a notable event was detected, the system listed it in the user interface. Through this notification, the system administrator was able to quickly learn the events. In FIG. 7, the system event was further reported its duplicate occurrences during various time windows. The system administrator could further set up the alert rule regarding this event. In FIG. 8, a customizable report (e.g., scheduled, instant) was generated regarding the event. In addition, more information (graphs, times, severity, devices, sources, time windows, etc.) associated with the event could be added the report. Referring to FIG. 9, the interface further allowed an administrator to invoke the knowledge database to explore what the event is about, and how to address the event. For instance, a network error message could be linked to a Cisco® knowledgebase for the system administrator to look up.

Example 5 System Configuration

FIG. 10 and FIG. 11 illustrate an example of system configuration. A system administrator can configure backups, times, reports. Furthermore, a data record in deduplicated log data can be linked to a map to display geographical information and IP information. In a setting, the system can trace the routes of an event over time or over routing addresses. Finally, notifications associated with an event can be set up.
